Definitions

  • This invention relates to knitted fabrics with excellent warmth-keeping and water-absorbing characteristics, and to a process for manufacturing the same.
  • the woven and knitted fabrics described in JP-A-61-28073 are composed of polyethylene terephthalate copolymer fiber containing 0.8 to 1.8 mol% of sulfo-isophthalic acid and rendered hydrophilic, and have a dual structure with a cover factor ratio ( front face to back face ) less than 0.8.
  • Fabrics of this type form pills after several times of wear and laundering. The pills thus formed tend to attach to other textiles during laundering and to intertwine with pieces of fiber released from these textiles, degrading their utility value. This trouble is particularly marked when fabrics of different colors are laundered together. In addition, pilling adversely affects warmth-keeping characteristics as well as the feel to the skin, making the affected fabric unsuitable for use as underwear.
  • the first object of this invention is to provide knitted fabrics suitable for garments, particularly autumn and winter underwear, made of polyester fiber which has hitherto been considered unsuitable for underwear.
  • the second object of this invention is to provide a process for manufacturing such knitted fabrics.
  • the first object of this invention can be achieved by a knitted fabric in which yarns are composed mainly of phosphorus-containing polyester spun yarns having an intrinsic viscosity of 0.36 dl/g or lower and subjected to hydrophilic finishing, whose weight is in the range from 120 to 460 g/m2, whose lateral stretchability is 100% or higher, whose contact coolness is 5.0 x 10 ⁇ 2 J/cm2/sec (1.2 x 10 ⁇ 2 cal/cm2/sec) or lower, whose warmth retention ratio for unit thickness is 105 or higher, and whose wicking rate (water-absorbing characteristic) measured by the water dropping test is less than one second.
  • the second object of this invention can be achieved by a process which comprises (1) making a knitted fabric from spun yarns composed mainly of phosphorus-containing polyester fiber whose phosphorus content is 0.5 to 1.5 mol% based on the total acid component, whose intrinsic viscosity is in the range from 0.30 to 0.45 dl/g, and whose content of acidic terminal groups is 80 ⁇ eq/g or higher; (2) treating the knitted fabric made above at a temperature of 100 o C or higher in the presence of water to reduce the intrinsic viscosity of said phosphorus-containing polyester to 0.36 dl/g or lower; and (3) applying a hydrophilic finishing agent durable to laundering to an add-on of at least 0.1 wt% based on the knitted fabric before, during or after the heat treatment, followed by drying.
  • Figure 1 illustrates the knitting structure of the fabric of Example 1 viewed from the pile face, in which numeral 1 is foundation yarn made of textured polyester filament yarns, and numeral 2 is pile yarn made of phosphorus-containing polyester spun yarns.
  • the knitted fabrics of this invention are made of spun yarns composed mainly of polyester staple fiber with excellent anti-pilling property as detailed later.
  • the spun yarns may also contain a small amount of other staple fibers, such as cotton and wool, but are preferably composed totally of polyester fiber in terms of both cost and characteristics.
  • Suitable knitting structures include pile fabric, sheeting, interlock fabric, circular rib fabric, eight-lock, reversible, fleecy fabric and quilting. Knitted fabrics of this invention may be best when it is pile structure.
  • Such knitted fabrics are composed of spun yarns alone as described above, but the best combination to ensure high warmth retention and high stretchability is the use of textured polyester filament yarns as the foundation yarn and of polyester spun yarns as pile yarn.
  • This combination provides a fabric having a relatively plain front face composed of textured polyester filament yarns and a soft, bulky and warmth-retaining back face composed of polyester spun yarns. It is preferable that the back face be further raised.
  • the front face although composed chiefly of filament yarns, shows soft and natural feel because part of the spun yarns in the back face surfaces in the form of pills.
  • the spun yarns used must be highly anti-pilling as otherwise heavy pilling would take place on the front face.
  • the polyester staple fiber constituting the knitted fabrics, particularly for underwear, of this invention must have an intrinsic viscosity of 0.36 dl/g or lower, preferably 0.35 dl/g or lower when measured in an equal-weight mixture of phenol and tetrachloroethane at 30 o C.
  • spun yarns are made of polyester having an intrinsic viscosity of, for example, 0.38 to 0.45 dl/g and containing a phosphorus compound as described later, a fabric is knitted by using, as pile yarn, the polyester spun yarns prepared above, and the fabric is treated at a temperature above 100 o C, preferably at 120 to 140 o C, for 10 to 90 minutes in the presence of water, thereby enhancing its anti-piling property.
  • This heat treatment may preferably be performed after fiber producing or knitting process, because the fiber strength would be lowered during the process due to the reduction in the intrinsic viscosity and the lowered fiber strength would cause various troubles: single yarn and tow breakage and fiber fusion during cutting in the staple fiber manufacturing process; significant reduction in production speed and formation of weak and uneven yarns in the spinning process; and frequent formation of needle defects and broken yarns in the knitting process.
  • the heat treatment should best be performed in the dyeing step in the form of knitted fabrics. Since fabrics are generally subjected to wet processing at 100 to 140 o C in the dyeing process, reduction of intrinsic viscosity to 0.36 dl/g or lower can be achieved by proper selection of dyeing temperature and time, and hence this heat treatment does not add to the production cost.
  • Use of the polyester staple fiber thus obtained gives highly anti-pilling property to underwear which is a kind of garment frequently laundered and which tends to form pills.
  • the phosporus-containing polyester fiber having such characteristics as described above may be produced as follows according to the method given in JP-A-61-47818 (March 8, 1986):
  • the organic phosphorus compounds of formula (I) have excellent polyester modifying effect and also possess the following characteristics: low degree of discoloration, little formation of ether bonding, less impurities formed in the polymerization system, low loss of phosphorus from the reaction system, and low cost.
  • a phosphorus compound of this type is added to the polymerization system in such an amount that the content of phosphorus will be 0.5 to 1.5 mol% based on the total acid component.
  • the phosphate molecules are incorporated into the polymer main chain during polymerization, and the phosphate linkages thus formed in the polyester chain readily undergo hydrolysis when heat-treated in the presence of water, thus serving to reduce the molecular weight of polyester and to exhibit anti-pilling effect.
  • the presence of acidic terminal groups such as carboxyl groups accelerates the hydrolysis of phosphate linkages.
  • the polyester staple fiber used in this invention should preferably contain at least 80 ⁇ eq/g of acidic terminal groups.
  • the alkyl group of the organic phosphorus compounds [I] should preferably have 3 to 8 carbon atoms. Phosphates of 1 to 2 carbon atoms lack in stability, while those of 9 or larger carbon atoms tend to discolor the resulting polyester.
  • the purity of the phosphorus compounds should preferably be 96% or higher to prevent discoloration, formation of many ether linkages and other troubles.
  • the mol % of phosphorus based on the total acid component is herein defined as the percentage of gram atoms of phosphorus contained in the polyester to the total mols of acid components used for the manufacture of polyester.
  • Polyester spun yarns used by this invention are obtained by spinning the above fibers by the conventional methods. In this invention, it is important for such fibers to have a size of 0.5 to 2.5 deniers and a length of 30 to 80 mm.
  • polyester filament yarns may be suitably used in combination with the highly anti-pilling polyester staple fiber detailed above.
  • These polyester filament yarns are made of polymer obtained by reaction of terephthalic acid or a lower alkyl ester thereof with a lower glycol, in which part of the acid component may be replaced with other dicarboxylic acid such as isophthalic acid, sodium salt of 5-sulfo-isophthalic acid, adipic acid and sebacic acid or a low alkyl ester thereof.
  • the glycol component is chiefly ethylene glycol, which also may be partly or wholly replaced, as required, by other glycol such as propylene glycol, 1,4-butanediol, trimethylene glycol, 1,4-hexanediol and neopentyl glycol.
  • the polyesster may also contain, as reqiured, additives such as titanium dioxide, silicon dioxide, alumina-related substances, tin oxide and carbon, and antioxidants, stabilizers, fluorescent brighteners and pigment.
  • the polyester is melt-spun into filaments, which are then texturized by known techniques, for example, false twisting.
  • the suitable size of textured polyester filament yarns used in this invention is 3.33 to 22.2 tex (30 to 200 deniers), preferably, 4.44 to 11.1 tex (40 to 100 deniers).
  • the fiber, particularly staple fiber, constituting a knitted fabric of this invention is rendered hydrophilic by treatment with a finishing agent durable to laundering.
  • the durability should be such that the wicking rate ( water-absorbing characteristic ) measured by the water dropping method, is one second or less after 30 times of laundering.
  • Typical examples of hydrophilic finishing agents showing such durability to laundering are low molecular-weight polyesters made from polyethylene glycol and terephthalic acid and having a structure represented by formula [II] below, wherein R is hydrogen atom or an alkyl group of 1 to 12 carbon atoms; R' is hydrogen atom, hydroxyl group or an alkoxy group of 1 to 12 carbon atoms; R'' is an alkylene group of 3 to 5 carbon atoms; x is an integer of 1 to 20; and y is an integer of 5 to 50.
  • R is hydrogen atom or an alkyl group of 1 to 12 carbon atoms
  • R' is hydrogen atom, hydroxyl group or an alkoxy group of 1 to 12 carbon atoms
  • R'' is an alkylene group of 3 to 5 carbon atoms
  • x is an integer of 1 to 20
  • y is an integer of 5 to 50.
  • finishing agents should be applied to such an add-on that the water-absorbing ability of finished fabric will be less than one second when measured by the water dropping method or 90 mm or larger when measured by the Byreck method. If applied under conditions other than the above, these agents may cause various troubles: stuffy feeling during wear when applied to underwear, build-up of electric charges, and others.
  • the suitable add-on to ensure satisfactory effects may vary depending on the type of finishing agent, and is in the range from about 0.1 to about 2%, most preferably, from 0.2 to 1% with SR1000 ( Takamatsu Oils & Fats ).
  • the knitted fabric applied with such a finishing agent is then dried and heat-treated ( dry or wet ) preferably at a temperature of 60 to 160 o C for fixation of the agent to the fiber. Fixation is insufficient at lower treating temperatures, while discoloration is likely to occur at higher temperatures.
  • contact coolness which is herein defined as the quantity of heat J/cm2/sec ( cal/cm2/sec ) instantaneously absorbed by a sample of knitted fabric held at 20 o C when a copper plate held at 30 o C is brought into contact with that knitted fabric.
  • This contact coolness which is determined by the surface characteristics of the material under consideration, is considered to depend on the knitting structure and to be changed by surface modification. We have succeeded in creating warmth by proper combination of these factors.
  • the knitted fabrics of this invention should have a contact coolness value of 5.0 ⁇ 10 ⁇ 2 J/cm2/sec (1.2 x 10 ⁇ 2 cal/cm2/sec ) or less, most preferably, 4.6 ⁇ 10 ⁇ 2 J/cm2/sec (1.1 x 10 ⁇ 2) or less in order to feel warm upon contact with the skin.
  • a contact coolness value 5.0 ⁇ 10 ⁇ 2 J/cm2/sec (1.2 x 10 ⁇ 2 cal/cm2/sec ) or less, most preferably, 4.6 ⁇ 10 ⁇ 2 J/cm2/sec (1.1 x 10 ⁇ 2) or less in order to feel warm upon contact with the skin.
  • a contact coolness value of 5.0 ⁇ 10 ⁇ 2 J/cm2/sec (1.2 x 10 ⁇ 2 cal/cm2/sec ) or less, most preferably, 4.6 ⁇ 10 ⁇ 2 J/cm2/sec (1.1 x 10 ⁇ 2) or less in order to feel warm upon contact with the skin.
  • 4.6 ⁇ 10 ⁇ 2 J/cm2/sec 1.1 x 10 ⁇
  • '' warmth retention ratio '' is herein defined as a ratio of the quantity of heat needed to maintain knitted fabrics at 33°C ( temperature of skin ) when it is cooled by blowing air ( 20°C, 50% R.H. ) at a speed of 0.1 m/sec to the corresponding value for 3-ply cotton interlock fabric taken as 100.
  • this value should be 105 or higher, most preferably, 110 or higher.
  • underwear must have a special knitting structure to include immobile air inside. A typical example is shown in Figure 1, in which looped or raised spun yarns are used on one face, thus securing immobile air mass in the loops.
  • the knitted fabrics of this invention should be designed so as to give a lateral stretchability of 100 % or higher, as otherwise one may feel hard and tight during wear and when putting it on or taking it off.
  • the weight of knitted fabrics of this invention be in the range from 120 to 460 g/m2 in terms of both performance and economy.
  • the knitted fabrics of this invention are far better than cotton and comparable to wool in warmth keeping ability, and are far inexpensive and easier to handle than wool. Much is expected of such knitted fabrics of this invention as an essential material for autumn and winter underwear. Other potential applications would be in the fields of T-shirts, knitted sportswear, training pants, towels, nightshirts, socks and stockings.
  • Dimethyl terephthalate ( 990 parts by weight ), ethylene glycol ( 790 parts ) and zinc acetate ( 0.2 part ) were charged in a reactor equipped with a fractionator, and the mixture was heated with agitation to 160 to 230°C for 3.5 hours while distilling off liberated methanol to effect ester exchange.
  • the product was transferred to a polymerization reactor, after which di-n-butyl phosphate of 97% purity ( 10.7 parts) and antimony trioxide( 0.4 part) were added, and the mixture was Polymerized at 280 o C for 2.5 hours under a reduced pressure of 0.67mbar (0.5 mmHg), giving polyester chips having an intrinsic viscosity of 0.52 dl/g and containing 1 mol % phosphorus and 3 mol% diethylene glycol linkage. The chips were melt-spun, drawn and heat-treated, giving staple fiber (1.5 d x 38 mm ) having an intrinsic viscosity of 0.42 dl/g and containing 100 ⁇ eq/g of acidic terminal groups. Polyester spun yarns of 40/1 cotton count were made from this staple fiber.
  • a fabric weighing 190 g/m2 as shown in Figure 1 was knitted on a circular knitting machine ( 24-gauge, 76.2 cm (30-inch)).
